Llama 3.3 70B is the previous Meta 70B open-weight workhorse. Teams still have it on disk. Llama 4 Maverick is the 2026 open flagship. The pair page is the upgrade conversation. If 3.3 still passes your eval and fits your GPUs, there is no trophy for migrating this week.
70B is a capacity class
People search “best 70b.” We do not have a parameter filter in v1. This news post plus the model page is the breadcrumb until we add one.
Empirical Evaluation & Architectural Analysis
Standardized telemetry recorded in the verified CompareLLM Leaderboards captures distinct architectural priorities between Llama 3.3 70B and Llama 4 Maverick. While blind human pairwise preference testing reflects instruction compliance and reasoning depth, domain-specific suites such as SWE-bench Verified and GPQA Diamond highlight coding execution and advanced STEM reasoning.
